摘　　要：Sun et al.,(1983)have given some favourable environmental conditions and have shown that there are four common features in convective rainstorms.In this paper,an important process of evolution of cloud systems was revealed when heavy rainfall occurred based on the diagnostic analysis of heavy rainfall cases.When the different cloud systems merge into a large one,the mesoscale heavy rainfall occurs and enhances.In other words,the process of evolution of cloud systems emphasized in this paper is the process of interaction between two cloud systems when the heavy rainfall occurs.The favourable environmental condition is also investigated.
